Capacitor in DRAM
Dynamic Random Access Memory (DRAM) uses capacitors as a key component for storing data. Here’s why capacitors are essential in DRAM:
- Data Storage: In DRAM, each bit of data is stored as an electrical charge in a tiny capacitor within a memory cell. The presence or absence of charge represents binary 1 or 0, respectively. This charge is continually refreshed to maintain the data, as capacitors tend to leak and lose charge over time.
- Read and Write Operations: Capacitors allow for quick read and write operations. When a cell is read, the charge in the capacitor is detected, and the data is retrieved. When data is written, the capacitor’s charge is modified to represent the desired value.
- Lower Cost: DRAM is cost-effective, and capacitors are a relatively inexpensive component in memory chips.
For the above reasons, need a capacitor in DRAM
